Louis Dupaigne and Alberto Farina
Vol. 15 (2022), No. 2, 551–566
DOI: 10.2140/apde.2022.15.551
Abstract

We classify stable and finite Morse index solutions to general semilinear elliptic equations posed in Euclidean space of dimension at most 10 and in some unbounded domains of dimension at most 11.

Keywords
semilinear elliptic PDEs, Liouville-type theorems, stable solutions
